Reducing feedback on your live set up
Posted by Rick Shao on 13 November 2015 06:27 AM
  • Always try to position the speakers so that they are in front of all microphones, pointing away from them. If you point speakers back at you, it will almost certainly cause feedback. If you have to point them back at you, try to position them to point directly at the back of the mic.
  • Make sure all mics are positioned correctly. One mic out of position can cause the whole problem.
  • Listen for the frequency of the feedback and try to adjust the EQ accordingly; if youre getting low end rumbles, turn down the bass on your mic channel or graphic EQ. If youre getting high squeals, turn down the treble on the mic channel or graphic EQ, etc.
  • You may need to add a monitor system so that you can hear yourself better. You can power these from your mixer, or use active stage monitors, and EQ them separately from the mains in order to maximize levels before feedback occurs. Point these back at yourself at ear level and you can turn down your mains to control the feedback better.
